Lead screw and the lamp: used to connect and slide into the carton box, and slide into carton movement and power passed into the box, the sliding box to get the vertical and linear motion. Lead screw is specially used for cutting all kinds of screw thread and fixed, used for other appearance of turning on the artifacts, polished rod only, without guide screw. Students should merge skateboard box items, in order to distinguish between light and guide screw.

tailstock: device on the lathe bed guide rail, and along the rail longitudinal movement, to adjust their job position. Tailstock is mainly used to top after device, to support a long piece, also can undertake machining device drill, reamer, etc. Bed: is the numerical control lathe with high precision guide rail, Yamagata guide peaceful guide) Grounded in a large part. Used to support and join the parts of numerical control lathe, and to ensure that all parts have a precise relative orientation in my homework. slide boxes: is the manufacturer of CNC numerical control lathe feed movement control box, the polished rod and screw rotation movement into the linear motion of the tool carrier groups, with polished rod transmission to complete the rest of the longitudinal feed movement, the transverse feed movement and rapid movement, through the screw driver tool holder vertical straight movement, so as to turn of thread.< br / >
spindle box: also called headstock, it is the main task of the main motor rotation movement coming through a series of variable speed organization make main shaft gets the positive and negative two to different speed, spindle box together gives impetus to the movement into the box. The spindle box of spindle is the key to the lathe parts. Spindle bearing on operation stability directly affect the machining quality of workpiece, when reduced, the spindle rotation accuracy is the use of numerical control lathe value will fall.< br / >

Improving Precision and Service Life through Fixture Adjustment and Maintenance
Fixture Adjustment Methods:
Fixture Maintenance Methods:
By properly adjusting and regularly maintaining fixtures, the machining accuracy and service life of Swiss-type lathes can be effectively improved, ensuring efficient and stable production processes.
The stress in a machine tool bed can influence machining quality in several ways:
Machining Accuracy
Deformation and Displacement: Stress in the bed can cause structural deformation, which in turn affects the positional accuracy of various machine components. For example, insufficient rigidity at the tailstock support of the bed may lead to positional deviations of the tailstock center, with maximum displacement deformation reaching up to 0.13465 mm. Such deformation directly impacts the relative positioning between the tool and the workpiece, resulting in machining errors.
In summary, the multi-process integration of Swiss-type lathes, achieved through advanced CNC systems, multi-axis linkage, power tools, and automation features, offers significant benefits in terms of precision, efficiency, and versatility. This integrated approach not only enhances production efficiency but also reduces costs, making Swiss-type lathes an ideal choice for modern manufacturing needs.
Differences in Machining Effects with Different Power Head Configurations
Single Spindle vs. Dual Spindle: Single-spindle Swiss-type lathes usually come with one side power head and are suitable for machining relatively simple parts. In contrast, dual-spindle lathes can be equipped with more power heads and can even perform simultaneous machining on the main and secondary spindles, significantly improving machining efficiency and complexity.
Side Tool Post vs. Horizontal Tool Post: Power heads with a side tool post structure perform better when machining difficult-to-chip materials, while those with a horizontal tool post structure are more efficient for machining easy-to-cut materials.
In summary, the power heads of Swiss-type lathes offer significant advantages in machining accuracy, efficiency, complexity, and adaptability. Different power head configurations can be selected based on specific machining requirements to achieve the best machining results.
Pitch compensation is an important means of precision improvement in CNC machines. By compensating for the pitch errors of the lead screw, it can significantly enhance the positioning accuracy and machining accuracy of the machine tool. The following is a detailed description of the methods, steps, and application cases of pitch compensation:
By implementing the above key points, Swiss-type lathes can achieve high-precision, high-efficiency linear positioning, meeting the machining demands of high-precision fields such as aerospace, automotive manufacturing, and medical devices.
